Introduction to C# and Visual Scripting

Unity has a lot of great built-in tools to solve the most common problems in game development, such as the ones we have seen so far. Even two games of the same genre have their own little differences that make the game unique, and Unity cannot foresee that, so that’s why we have scripting. Through coding, we can extend Unity’s capabilities in several ways to achieve the exact behavior we need, all through a well-known language—C#. But aside from C#, Unity also has Visual Scripting, a way to generate code through a node graph tool. This means you can create scripts without writing code but by dragging nodes, boxes that represent actions that can be chained:

While essentially both ways can achieve the same result, we can use them for different things. Usually, the core logic of the game is written in C# due to it being usually huge and very performance sensitive...
